I also have Version 4.0.0.20589. However, it doesn't work for me. I am using the Ardennes Assault trainer from 06.24.2015.

-I am using no firewall, running in admin mode, etc. -I hit F1 at the main menu and hear "Trainer Activated" like everyone else. When I enter the game I hit 1, 2, and 3 and will hear "activated" after about 2 minutes. However, nothing happens. -If I hit number 4, the entire game crashes.

I have trouble with some functions in the trainer.First of all, can somebody explain why it takes a while for trainer to become active after you activate the trainer at main menu. like, after you press F1, the trainer says "Trainer activate -- Please wait.." and then you have to wait like 5 mins to be able to use trainer.Secondly, what's going on with the instant build or train function? it deactivates itself immediately after I activate it. Can somebody point this out?
